<![CDATA[running out of swap space]]>Today I started running out of swap space after about 5 minutes from boot. At which point new devices can't connect and I can't use ssh or web gui unless i reboot.

Those are the only packages installed now. I uninstalled suricata and PFblockerNG

It seems like it is /usr/lib/sys/rcu_bj but I am not sure what that is.

How do i check for the gui being exposed to the internet?

Check the WAN rules (another recent poster had a block rule but it was using a Source of WAN Address, so was completely open). [edit: because they had also added an allow all rule 🤦 ]

Check the GUI Service log at https://xxxx/status_logs.php?logfile=nginx for public IP addresses.

I created a WAN firewall rule to block https traffic to the IP of the system. changed the port and turned off ssh access and moved from a 12 character to 30+ character password.

I reinstalled and upgraded from 2.6 to pfsense+ 23.01 as well and reconfigured pfblocker.

Probably will do a full reinstall and drive format and restore my config from xml just to be sure.
